Model a 32-bit ALU that can perform the following operations in behavioral Verilog: Control Line Operation 0 Addition 1 Subtraction This module has three inputs: two 32-bit signed numbers represented in 2's complement format (A & B) and a 1-bit control (CTRL). It produces a 32-bit result (R). Verify the functionality of the model. Use the following test vectors for the simulation results that you submit: Addition & subtraction A = FFFFFF00 B = FFFFFFFF A = FFFFFFFF B = 000F00FF A = 98998998 B = 51416270 A = AAAAAAAA B = EFABCD12 A = FFFFFFFF B = 00000001 A = FFFFFFFF B = FFFFFFFF A = 80000000 B = FFFFFFFF You need to provide the following items as 1 PDF file. Synthesizable Source Code; 50 points A test file. Use $monitor, $display, $finish, and proper delays in your test files clearly illustrate the correct functionality of each module; 30 points Simulation results (The text log generated by the testbench). 20 points
